Heat-pump-based device for temperature control has additional feed line to evaporator connected in parallel with expansion valve

摘要

The temperature control device has a coolant circuit including, in series, a compressor (1), a condenser (3) to yield the heat, and expansion valve (4) and an evaporator (5) to receive heat. The evaporator has an additional feed line (45, 46, 47) connected in parallel with the expansion valve, branching off from the input side of the expansion valve to feed the evaporator.
